Patented June 16, 1936 UNITED STATES PATENT OFFICE Application February 14, 1935. Serial No. 6,476 In Great Britain February 22, 1934 9 Claims.

The present invention relates to type racks of the kind including carriers of channel or slotted tubular form and the object of the invention is to provide a new or improved type rack, wherein the said tubes or carriers full of type may be mounted, the rack being constructed so that the type can be withdrawn one by one in a convenient manner for use, and the empty carriers removed and replaced by loaded carriers as required.

Referring to the drawings:-

Figure 1 is a front elevation showing a type rack or support according to the present invention.

Figure 2 is a sectional plan view of same.

Figure 3 shows same in sectional end elevation. Figure 4 is a perspective view of one end of one of the type carriers illustrated in Figures 1 to 3.

Figure 5 is a perspective View of the lower bar of the support illustrated in Figures 1 to 3.

Figure 6 illustrates the arrangement of a plurality of supports in a cabinet or framework.

In the construction illustrated in the accompanying drawings the apparatus comprises a cabinet or structure 8 in which a number of supports are arranged in inclined but spaced parallel planes, as shown in Figure 6, the forward edges of all the supports being disposed in a substantially vertical plane adjacent the front of the cabinet or structure so that ready access can be obtained to all the supports.

Each support comprises an open frame 9, each side or arm of which is of angle section, the top of the frame being disposed in a common plane and being adapted to support type carriers 10 for receiving the type.

Each carrier is in the form of a slotted tube or channel and is pressed from a blank or strip of metal to the section shown in Figures 2 and 4,

the edges of the blank or strip being bent to project inwardly across the channel to form overhanging edges for engaging in the reduced waist portions i l of the type I2, as shown in Figure 2.

The tail pieces of the type are received within the tubes or channels, whilst the type surface projects from the carrier tubes.

The rear surface or side I3 of each carrier is flattened to seat firmly upon the support and in this flattened side and at each end of the carrier is provided a longitudinal slot l4, shown clearly in Figure 4.

Along the lower side of the frame 9 is secured, by means of screws IS, a supporting bar l6 provided along its upper edge with a number of projecting tongues I1 which extend transversely of the bar in spaced but parallel relationship and at positions corresponding with the desired positions of the carrier tubes upon the support.

Each tongue H is of reduced width at its upper 5 end and at its lower end is under cut or of dovetail section and each carrier tube is mounted in position by engaging the slot I4 at the lower end of the carrier with one of the tongues l1. The reduced upper end of the tongue permits the 10 carrier to be engaged readily therewith, but when the edges of the slot I 4 engage with the dovetailed lower portion of the tongue the tube is retained in position upon the support.

Below the tongues l1 the bar I6 is recessed at 15 I8 and a rail is is secured in this recess by means of rivets 20. v

The rail is is formed with a plurality of delivery chutes 2| which extend transversely across the rail in parallel relationship and at spacing 20 correspondingwith the spacing of the tongues ll, such that when the rail I9 is secured to the bar It each chute 2| is aligned with one of the tongues l1.

At the lower edge of the bar 16 and projecting 25 from the latter at the lower side of the recess 1 l8 are a number of integral stop projections 23 also located in alignment with the projections l1, so that when the rail I9 is mounted in position each of the projections 23 is located directly beneath 30 one of the chutes 2! to form a retaining stop.

The rail I9 is cut away along its lower edge to provide a gap between the lower end of the chutes and the upper surface of the stop projections 23 and this cut away portion is stepped 35 or of varying width, as shown in Figure 1, so that the gaps between the various chutes and their corresponding stops are of different widths.

Each chute 2| is of enlarged or diverging form at its upper or inlet end 24 to facilitate the pass- 40 age of type from the carrier tubes into the delivery chutes when the rack is assembled as shown in Figures'l and 3.

Along the upper side of the frame 9 is secured a further bar 25 provided with integral projec- 45 tions 26 at spacings corresponding with the spacings of the tongues H, the arrangement being that when the lower end of a carrier tube has been engaged with one of the tongues H, the slot at the upper end of the tube can be engaged over 50 the corresponding projections 26 so that the tube is located at both ends relative to the support.

The projections 26 are not of dovetail or under cut section so that the carrier tubes can be pressed into engagement with the projections 26 55 til after they have been completely engaged with the tongues ll, but by making the projections 26 of width slightly greater than the normal width of the slots M at the upper end of the carrier tubes, the latter can be sprung into engagement with the projections 26 and retained by the resilience or spring in the end of the tube itself.

If desired, however, the projections 26 may be slightly under cut to facilitate retention of the carrier tubes.

Each carrier tube is loaded with type of a particular kind and is then mounted upon the support by first engaging the slot at the lower end of the tube with the corresponding tongue l1, and when the carrier is in position with its lower end adjacent the upper end of the delivery chute the slot 14 at the upper end of the tube is engaged with the corresponding projection 26 by pressing the tube over the projection which springs between the edges of the slot.

The type in the carrier slide down by gravity into the delivery chute which forms a continuation of the carrier and receives the tail pieces of the type, whilst the overhanging edges of the chute engage in the reduced waist of the type.

The lowest type in the delivery chute drops out of the lower end thereof and comes to rest upon the corresponding stop 23 and the carrier tube for the particular type is located upon the support in such a position that the gap between the lower end of the corresponding delivery chute and the upper surface of the stop is of width equal to or greater than the width of face of the particular type, but is less than twice the width of the type face.

Thus, only one tape at a time can move out of the lower end of the chute and until the lowest type is removed the remaining type are retained either in the carrier or in the delivery chute.

In connection with printing machines of the kind known as oflice appliances, it is usual to employ type which are all of the same width, but the present invention is primarily intended for type for use in commercial printing machines, wherein the width of the type varies considerably.

Thus, it is necessary to arrange the carriers at suitable positions upon the support so that the gap at the lower end of the delivery chute is of suflicient width to accommodate one type, but is insufficient to enable the two lowest type in the delivery chute to be free. It is not essential that the gap should be of width exactly corresponding with the width of the particular type as long as only the lowest type is entirely freed from the delivery chute and the next succeeding type is engaged to some extent in the end of the delivery chute.

It is thus possible to arrange the steps in this gap in a number of average widths so that types of widely differing widths can be accommodated in one or other of the chutes.

The type can be removed from the support by sliding the lowest type of the desired kind from the bottom of the corresponding column and when this lowest type has been removed the next lowest drops into the delivery position and any number of type can be fed in succession from the delivery chute, although it is impossible to obtain delivery of two type simultaneously from the same chute or carrier.

When the supply of type from any particular carrier tube is exhausted, the empty tube can be removed and a number of this particular type are available in the corresponding delivery chute pending the replacement of the empty carrier by a full carrier of type.

Any carrier can quickly be removed from the support and a loaded carrier can be mounted in the correct position with the minimum possible delay, but if desired, manually operable means may be provided for retaining the upper ends of the carrier tubes in position, such for example, as small spring pressed bolts mounted upon the upper bar 25 or the upper side of the frame 8.

The present invention is primarily intended for use with dwarf type, i. e. type having very short stems.
